Wooster, Ohio. It is hardly necessary to state that our results 
could not have been attained without this splendid cooperation, 
which we are pleased to acknowledge here. Later in the season 
(beginning, in 1931, about July 4) the American chestnut sprouts, 
of which there are many in this vicinity, open up their flowers, and 
this pollen was used (in part) for the last pollinations. 
clnalysis of Results in 1931—The results this year (Table IT) 
show that 24.5 per cent., or nearly one quarter of all the branches 
pollinated, bore nuts. 15 per cent. of all the pistillate flower 
clusters on the branches bore nuts—many of the burs having two 
or even three nuts. In one case one branch on the Smith tree 
— 
bore nine nuts in four pistillate lowers. In other words, four burs

were formed on this branch. Two of the burs contained three 
nuts each; one, two nuts; and the fourth, one. It is significant 
that this branch was located near the top of the tree, where pol- 
linations were made in order to determine whether the results 
would be better here than in more accessible branches, which could 
be reached either from the ground or from a step-ladder. Of the 
seven branches pollinated near the top of this tree four yielded 
late flowers pollinated on these seven 
— 
nuts, and of the 26 pisti 
branches ten yielded nuts. These results show a much higher 
percentage of success than the average for this tree. Only further 
work, however, can determine whether this is the general rule. Of 
course the operation becomes much more difficult if one has to 
le season.
